Astrodynamics is a computation exercise of space objects, either analytically or numerically. Traditionally the primary objective is to compute trajectories with both the highest speed and accuracy. DerAstrodynamics adds robustness to the analytic algorithms of Kepler, Vinti, and Lambert. Numerical integration techniques, which have been neglected faster than the computer clock speed, are blindly applied in black-boxes. Real-time Space Situation Awareness and Multiple Hypothesis Tracking is ineffective with numerical integration of trajectories for thousands of objects.

Trajectory Prediction can be computed not just by the analytic Astro-Standard SGP4 algorithm, but the analytic Vinti algorithm as well. Unlike the SGP4, the Vinti algorithm has no singularities, and can be applied to both satellites and missiles.

DerAstrodynamics provides simple, precise and concise algorithms, and computer source code in Fortran and C with end-to-end applications as numerical examples.

All Primary Algorithms are available now, and others are coming soon!
